Abstract

The invention relates to the field of outdoor sports products and discloses a quick time service watch based on a Beidou No.3 system. Creation through the invention, the novel satellite watch for solving a problem of slow satellite time service based on a Beidou No.3 system is provided, on one hand, by independently supplying power to an RTC power supply in a satellite module, after the watch is reset or turned on and off, ephemeris and other information in the module and obtained through last positioning can be stored, then positioning or time service is carried out later, and the resolving speed of satellite signals is greatly increased, on the other hand, the time, minute and second information of the current time can be obtained by calculating the intra-hour second counting, intra-weekhour counting and whole-week counting in a B-CNAV1 navigation message of the single satellite, so the time service can be quickly completed, and user experience is improved.

Description

technical field [0001] The invention belongs to the field of outdoor sports products, and in particular relates to a fast timing watch based on the Beidou No. 3 system. Background technique [0002] With the successful launch of the 42nd and 43rd Beidou navigation satellites at the Xichang Satellite Launch Center on November 19, 2018 (these two satellites are the eighteenth satellites of my country's Beidou-3 system) , 19 networking satellites), marking the successful completion of the basic system space constellation deployment task of my country's Beidou-3 global networking. At the press conference held by the State Council Information Office on the afternoon of December 27, 2018, Ran Chengqi, director of the China Satellite Navigation System Management Office and spokesperson for the Beidou Satellite Navigation System, announced: "The basic system of Beidou-3 has been completed and will begin to provide global services today. ". [0003] The new generation of Beidou-3 sy...
